After Neel's crew has left, some timber framers stay behind
to help finish the swinging-weight trebuchet. Frenchman Renaud
Beffeyte, a restorer of ancient castles, was guided in his
design of this trebuchet by medieval drawings and writings.
Instead of using lead weights, this machine relies on a huge
hinged bucket that can be filled with available rubble or
dirt—a far more convenient design for medieval armies.
The machine is even more massive than its counterpart.
